Flashcards in Lecture 1 Deck (117)
What is included in a PE for FNA exam (foot and ankle)
What is included in the imaging for FNA exam?
Yeah thats what the slides say
Stance phase includes:
Swing phase includes:
What causes a lack of normal push-off?
What causes the increased external rotation?
Besides watching them walk, how else should you assess gait?
- heel and forefoot wear
- heel counter wear
- toe scuffing in foot drop
transcutaeous oximetry (PtcO2) <40 mmHg?
Impaired wound healing
Transcutaneous oximetry (PtcO2) <30 mmHg?
Signs of vascular changes on the FNA exam?
What are you checking for with fna palpation?
What is equinus contracture
Limited ankle dorsiflexion not caused by bony impingement
What conditions are implicated with equinus contracture?
What is silfverskiold test?
Assess the isolated gastrocnemis vs the gastrocnemius-soleus contracture
Test knee in full extension and at 90*
Silfverskiold test gastroc tightness?
Improved ankle dorsiflexion with knee flexion = gastroc tightness
The gastroc is the more superficial calf muscle (soleus is deep) and so bending the knee isolates it and differentiates between the two for exam
Flexible toe deformities
Hypermoble 1st ray
What is the normal apex of the foot when weight bearing?
Normal apex of 1 cm when weight bearing
Types of foot apex disorders?
Planus - flat foot
Cavus - high arch
Rocker bottom - shit show
Causes of planus problems?
PTT dysfunction c
Causes of cavus problems?
Causes of rocker bottom alignment?
Congenital vertical talus
What will looking at a person’s foot from behind while weight-bearing?
Too many toes sign
You should see 1-2 toes, if you see more its a valgus hindfoot problem
What is the coleman block test?
Assess the flexibility fo deformity of varus hindfoot
The block will correct the deformity if it is secondary to plantar flexed first ray
What tests are used to ID syndesmotic (high ankle) injuries?
Squeeze test (88% specific)
External rotation test
What does anterior drawer test assess?
The anterior talofibular ligament (ATFL)
How is the anterior drawer test of the ankle performed?
Ankle is at 20* plantar flexion and knee is flexed at 90*
What does the talar tilt assess?
Calcaneofibular ligament (CFL) in neurtral position
Anterior talofibular ligament in plantar flexion
How is the talar tilt exam performed?
Inversion force to hindfoot
<5* is normal
What is the achilles tendon comprised of?
